Abstract
The purpose of innovations is to increase the efficiency of work procedures, accommodating sustainability and efficiency trends. One of the preconditions of technological innovations is development of construction products. A prefabricated board with built-in infrared heating is an innovative product which reduces labour intensity at the construction site by featuring a heating system that is built directly into the construction board, which begins to perform its function immediately after it is built in. This article presents certain partial results of the research and development of an innovative board with built-in infrared heating, which is currently protected by a valid utility model. Nine material variants of the innovative board were analysed as part of the experimental research. The research focused on the pattern of changes in surface temperature over time. The results of the experiment, despite deviations from the anticipated behaviour of the individual boards, showed a link between thermal resistance and increase in surface temperature.
